You would be more humble than you are at present, for one. For two, you wouldn’t be inadvertantly casting aspersions upon another church on the basis of beliefs that are shared by your own.
You’re clearly not all that authoritative on those beliefs, let alone any Protestant denomination.
I suggest sticking with what you know.
Why should I have to do that, when anti-Catholic bigoted Presbyterians insist that Catholics worship Mary? They go right ahead and say whatever they want, hold themselves to no standard of truth, and insist that they know Catholic beliefs better than Catholics do.
So, I feel no constraint to find out anything about the bigots before posting about them. Their beliefs are boring: You Live, You Die, by God’s Will you will go to heaven or hell, nothing you do makes any difference, so, for the love of Christ Jesus, do NOT pray to His mother, she’s Jewish you know.
